MORPHOMETRIC PARAMETERS OF THE LABYRINTH SEGMENT OF THE FACIAL CANAL IN PEOPLE WITH DIFFERENT CRANIAL INDEXES

Abstract

Based on the analysis of computed tomograms, the article assesses the morphometry of the labyrinth segment of the facial canal of different age groups – its length and diameter, depending on the shape of the skull (in terms of the transverse index). The material for the study was 133 tomograms taken from the archive of the radiological department of the Educational-Surgical Clinic and the Department of Radiation Diagnostics and Therapy of the Azerbaijan Medical University. The material is divided into age groups: group I (7-12 years old), group II (13-16 years old), group III (17-21 years old), group IV (22-35 years old), group V (36-60 years old) and group VI (61-74 years old). The obtained data showed that the length of the labyrinth segment in brachiocranes (wide skull) is greater than in mesocranes (medium skull) and less than in dolichocranes (long skull). The greatest difference was mainly observed on the left. When comparing age groups, it was found that the length of the labyrinth segment is greater in age groups I-III and less in group VI (over 61 years old). To estimate the diameter of the labyrinth segment, the measurements were taken near the entrance to the facial canal. The diameter of the labyrinth segment of the facial canal was 3.5-5 times smaller than the diameter of the internal auditory canal, regardless of the shape and size of the skull. In brachiocranes, the diameter of the internal auditory canal is smaller in age groups III and V. The largest diameter of the internal auditory canal is observed in dolichocranes on the right and left.
